UNITED STATES PATENT A OEEICE.

JAMES K. FAIRBANK, OF WAUPUN, WISCONSIN.

IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 4I,764, dated March 1,1864.

' proved Pump; and I do hereby declare the following a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of refer ence marked thereon, in Which-Figure lis an external representation ot' the pump, and Fig. 2 avertical section through the center thereof.

To enable others skilled in the art to make and use my invention, I Willproceed to describe its construction and operation.

I take the ordinary pump stock and bore it of sufficient diameter toadmit a. glass, stone, or metallic cylinder, A, said cylinder beingsecured to the stock by cement B. I also employ the metallic strap D onthe upper portion of the pump-stock to prevent the same from splitting,to Which it is ever liable, and at the same time furnishing the bestmode of fastening the handle,v the straps D crossing the pump in onedirection, as represented in the drawings, and fastened by bolts f f atright angles to said straps,and passing through the stock from side toside.

The pump as thus constructed is much more durable, the water purer, andits operation easier and repair less frequent than the ordinary pumprequires. The plunger U can be inserted or Withdrawn at any time Withoutdisturbing the pump unless it is a very deep Well.

I am aware that it is not new to line the interior of a pump-stock witha material more ing and retaining a smoother surface; but,l my inventiondiffers from others of its class in that the interior cylinder is adjusted to its position by means of an intermediate layer of cement,which, with the interior cylinder, rests upon the next lower length orsection 'ot' the pump stock, Whichtits into that containing the innercylinder, as shown in the drawings.

What I claim as new, and desire to secure by Letters Patent, is

A pump having an interior cylinder adjusted in the manner set forth, andalso the bandsB B and bolts ff, arranged to strengthen the upper part ofthe stock and afford bear- `ings for the handle, all as shown anddescribed.
